The Elements 112C series systems are two-way speaker systems comprised of a 12 Water-Resistant Black Widow woofer and an RX22 2 titanium diaphragm compression driver mounted on a constant directivity horn utilizing Quadratic Throat Waveguide technology. The Elements 112C speaker system has a trapezoidal shaped enclosure, which reduces the build-up of standing waves inside the enclosure, which minimizes mid-bass and mid-range coloration s due to the cabinet. They are constructed of 12mm advanced technology composite fiber panels and are coated with a black Hammerhead poly-urea finish. An 18 gauge powder-coated perforated stainless-steel metal grille with an inner hydro-phobic cloth mesh, and a foam third layer protects the front of the system from external moisture and dust. A full set of twelve 3/8"-16 threaded mounting suspension points, 3 each top and 3 each bottom, and 2 each sides & back is provided for flying and mounting, as well as three sets of 4) 1/4X20 SS inserts, the sets are located on the top, rear, and bottom for use with the Peavey Versamount 70+ and the Peavey Elements Pole Mount bracket. 3

4 They have a water-resistant version of the high power Black Widow WR woofer incorporated, with a resin impregnated cone and dust cap for superior environmental stability. Capable of over 500W of continuous power handling (AES Std ), the weather resistant woofer can handle a lot of sheer power. The high frequencies are handled by a RX22 2 titanium diaphragm compression driver, utilizing ferrofluid cooling, coupled to either a 60X40 degree or a 105 X 60 degree constant directivity horn utilizing Quadratic Throat Waveguide technology. The Quadratic Throat horns are protected under US Patent 6,059,069, and due to this patented geometry, these horns have lower distortion than many popular CD horns. The RX22 driver features the Radialinear Planar Phase Correction System, under US Patent 6,064,745, which provides smoother and extended high frequency response. Input connection to the system is made via a pair of 4 pin Neutrik NL-4 connectors in parallel with a corrosion-resistant 4-position screw terminal strip for input connection flexibility while maintaining superior signal integrity. A sealed cover plate with a gland nut protects the input cup connectors from the environment. The passive crossover includes the Peavey Sound Guard tweeter protection circuit in the high frequency driver signal path, to provide long term reliability. Peavey s proprietary high-frequency driver protection circuitry, Sound Guard, provides long and medium term driver overload protection, without impairing musical transients or dynamics. The internal passive crossover is conformal coated for maximum reliability, and utilizes weatherresistant internal connectors to assure outdoor reliability and a long service life. An Indoor/Outdoor EQ option is accessible externally from the input cup, and provides the ability to tailor the sound to the needs of outdoor use versus indoor use. A field installed transformer option is available, providing an easy upgrade to 70V/100V transformer use. The transformer is pre-mounted on a plate, the cover plate is unscrewed and removed from the Elements 112C, and the plate mounted transformer installed internally in it s place, with the simple un-plugging and plugging of water-proof connectors. The transformer option available for the Elements 112C has a 400W, 200W, 100W and a 50W tap. Despite it s compact dimensions for a 12 two-way enclosure, this system can put out some serious sound levels, and take large amounts of clean amplifier power, resulting in precise coverage with excellent clarity and high reliability. Flying or Mounting the Elements Enclosure Using the 3/8 inserts and corresponding eyebolts Caution: Before attempting to suspend this speaker, consult a certified structural engineer. Speaker can fall from improper suspension, resulting in serious injury and property damage. When using the 3/8 inserts and corresponding eyebolt rigging, other enclosures may be suspended below one Elements 112C cabinet. However, the combined weight of additional enclosures and all cables, clamps and other hardware must not exceed 248 4

5 pounds. The Elements 112C weighs 52 pounds and the maximum combined weight suspended from the uppermost mounting bracket assemblies must not exceed 300 pounds. Maximum enclosure angle 45 o. Use only the correct mating hardware, 3/8 X 16 threads per inch eyebolts or hex head bolts, with suitable ratings (Forged shoulder machinery eye bolt, MIL Spec MIL OR compliant with ASTM A489.). Rubber washers are provided for use with the 3/8 eyebolts, to assure a weather tight seal, and they should be used. All associated rigging is the responsibility of others. Always use a suitable safety chain or wire rope, attached to an unused group of fly points, and firmly attached to a suitable structural member as indicated by a certified structural engineer. Never transport the cabinet while mounted on an array bracket or other mounting bracket, this may unduly stress the mounting inserts. The use of threadlocker (blue type/medium strength) on the mounting bolts is recommended, to insure that the mounting hardware will not vibrate loose over time. Using the VM-70 Mounting Bracket Caution: Before attempting to suspend this speaker, consult a certified structural engineer. Speaker can fall from improper suspension, resulting in serious injury and property damage. Other enclosures may NOT be suspended below one mounted using the VM70, nor should additional weight be suspended from one of these units. The bolts supplied with the VM70 mounting bracket are grade 5 steel bolts, these should be replaced with Stainless Steel bolts, 1/4X20, SS alloy 316 or 18-8 (304). The length should be from 7/8 long to 1 1 / 4 long. The wall or beam mounting point for the other end of the VM70 bracket should also use the proper corrosion resistant fasteners. Always use a suitable safety chain or wire rope, attached to an unused group of fly points, and firmly attached to a suitable structural member as indicated by a certified structural engineer. Never transport the cabinet while mounted on an array bracket or other mounting bracket, this may unduly stress the mounting inserts. The use of threadlocker (blue type/medium strength) on the mounting bolts is recommended, to insure that the mounting hardware will not vibrate loose over time.

Care & Maintenance Designed to be installed outdoors, with direct exposure to the weather, there are still some things that can be done to help maintain the appearance and performance of your Elements speaker system. If possible, install in a location that is out of direct sunlight exposure, this will help reduce any fading or bleaching of the finish and hardware over very long periods of time. If the speaker is installed near salt water, then a once a week rinse off with clean fresh water will help maintain the appearance of the finish and hardware. A light, lowpressure rinse-off is all that is needed to be helpful. Connecting the Elements C series loudspeakers for outdoor use with the barrier strip and cover plate For connection to the Elements C series speaker system outdoors, the use of the barrier strip is recommended. 6

7 Procedure 1. Only remove a small length of the overall outer cable jacket, approximately 1.5 to 2 long. 2. The stripped and tinned ends of the individual wires only need to be long enough to go under the flat washer on the barrier strip, this length is approx. 5/16 to about 3/8. Use lead-free silver solder for the tinning, see below for more details. 3. Once the speaker cable has had the ends tinned, install the gland nut onto the cover plate. You will need to hold the outer gland nut base with a pliers or socket wrench to fully tighten the gland nut inner jam nut portion tight up against the plate. DO NOT overtighten the gland nut base during cover plate installation! Then loosely screw the gland nut compression nut to prepare for cable insertion and final tightening. 4. Now thread the cable through the gland nut, and leave about 7 of cable and jacket sticking out past the inside of the cover plate. Then tighten the gland nut down firmly till it seals against the cable jacket. You may need to hold the outer gland nut base with a pliers or socket wrench to fully tighten the gland nut compression nut down firmly against the cable jacket. This is enough length of cable inside the cover plate to allow the cover plate to pivot out of the way while the wires are being tightened down at the barrier strip. 5. Remove the 8 thumb screws from the periphery of the input cup recess, these will then hold on the cover plate once it is in position. These are the large head screws with a single slot in the head. DO NOT REMOVE THE INPUT CUP RETAINING SCREWS (small Phillips head screws) AROUND THE OUTER FLANGE OF THE INPUT CUP! Do not drop or lose the thumb screws. 6. Place the cover plate rubber gasket over and past the tinned wire ends of the cable, and then tighten the wires firmly under the barrier strip flat washers, but do not apply so much force as to distort or damage the barrier strip washer or screw. 7. Coat the exposed wires and terminals with an anti-oxidant compound or other protective coating for best long-term results. DO NOT USE RTV SILICONE RUBBER, AS THIS COULD CORRODE THE PARTS OR WIRES! Petroleum jelly, WD-40, and anti-oxidant compound as used on aluminum electrical house wiring are examples of such a protective coating. 8. Once the wires are tight under the barrier strip washer, the cover plate with it s rubber gasket can be fully installed. Use the thumb screws that were removed earlier, and carefully position the rubber gasket in between the cup and the plate around the edge, so it will seal properly. Position the 7 of cable to curve around inside the cavity formed between the input cup recess, and the cover plate, so the cable does not get caught under the rubber gasket or the edge of the cover plate. Then tighten the thumb screws firmly so as to seal the cup terminals under the cover plate and gasket. 7

8 NOTES: Solder alloy to use for tinning Use lead-free silver alloy based solder (typically an alloy of 96% tin, 3.5 to 4% silver and traces of some other metal such as copper or indium, etc.) to help reduce any corrosion issues with the screw terminal barrier strip parts. Length of cable inside cover It is possible to pull the cable through the gland nut while it is still loose, and put the cover plate on, and then tighten down the gland nut, but this does not allow enough strain relief for the cable, and would make it difficult to remove the cover plate without first loosening the gland nut, and this is not something that you can expect a future Service person to know to do first. It is strongly recommended that the full 7 of cable past the cover plate on the inside of the plate be allowed for and used. Gland Nut Cable Diameter Range The gland nut can seal an outer cable jacket diameter in a range from to Cables used to hookup the Elements speaker system should be of a sufficient gauge to handle the power they will be used with, have an outdoor rated jacket material and thickness, and the resultant cable jacket diameter should then be larger than This product is manufactured under U.S. patents 6,059,069 and 6,064,745. Exposure to Salt Spray or other Corrosive Environments Contact Peavey Electronics for use of the Elements enclosures when the speaker and mounting hardware will be exposed to salt spray or other corrosive environments. In general, eyebolts and mounting bolts should be changed to a rigging grade Stainless Steel 316 alloy. 8
